Unable to compile RDMA-aware examples in C

Unable to compile RDMA-aware examples in C

[floaterions]

Hello everyone,

I'm trying to run some basic rdma examples (provided here:
github.com/tarickb/the-geek-in-the-corner/tree/master/01_basic-client-server
but I keep getting these errors:

I'm guessing some missing libraries are responsible here.
Any help would be greatly appreciated.

Yes, you need install some lib. eg:
RedHat (RHEL 6.4 and above)

yum groupinstall "Infiniband Support"
yum install libtool autoconf automake
yum install infiniband-diags perftest libibverbs-utils librdmacm-utils
yum install librdmacm-devel libibverbs-devel numactl numactl-devel
libaio-devel libevent-devel


Ubuntu (Ubuntu 13.04 and above)

apt-get install libtool autoconf automake build-essential
apt-get install ibverbs-utils rdmacm-utils infiniband-diags perftest
apt-get install librdmacm-dev libibverbs-dev numactl libnuma-dev
libaio-dev libevent-dev

Move the -l<lib> at the end of your command line:
$ gcc -Wall -g server.c   -o server -lrdmacm -libverbs -lpthread
